Patent EP-0493052-A2 (EP)
Inventor: SWEET RICHARD G
IPC: B41J2/14
Filed: 1991-12-23
Abstract: A nozzleless droplet projection system is disclosed. A thin film of fluid (26) with a constant thickness travels at a constant velocity across a tubular transducer head (16a, 16b). A smooth perimetrical surface (18) is formed between the input (22) and the output (24) sides of the transducer head (16a, 16b). An array of electro-acoustic transducers (15) submerged beneath the transducer head support surface (17) generate tone bursts (20, Figs 3 and 4) of acoustic energy which are focused by a corresponding array of acoustic lenses (19) inscribed along the length of the transducer head (16a, 16b). The constant thickness and constant velocity fluid film (26) is generated by forcing pre-regulated, pressurized fluid through a narrow slit (30) and across the smooth perimetrical surface (18) of the transducer head (16a, 16b). The fluid film (26) is maintained at the acoustic focus of the lenses (19) in order to control the resultant droplet (12) size. A pattern of droplets (12) is ejected by pulsing the appropriate electro-acoustic transducers (15) as the projection medium (14) is moved across the droplet formation apparatus at a constant velocity.

Abstract: The invention relates to a bar tension sensor, preferably for cyclically operating production machines, such as for example for injection-moulding machines. 
<??>To monitor the clamping force during the injection operation, the tensile forces of the usually four tie bars (14) are continually and cyclically monitored. For this purpose, thin-disc force sensors (19) are fitted underneath the tie-bar tension nuts (13), the installation of which sensors requires no machining of the tie bars (14) or of the tension nuts (13), since they substitute standard shims and have virtually the same strength and flexibility values. The thin-disc force sensors (19) preferably operate on the piezoelectric principle on the basis of quartz crystals, ceramics or other crystals (24). In principle, the thin-disc force sensor (19) comprises a perforated metal disc (21), in which preferably a plurality of preassembled measuring elements (22) are fitted and are ground over with the metal disc (21) after they have been welded in. Consequently, the measuring elements (22) are parallel-connected in terms of force to the metal disc (21), in other words they measure a precisely defined component of the overall force. This component can also be increased by raising the measuring elements. For calibration of the overall system, a calibrating sensor (31) is fitted between the platens (33) and is connected to the measuring electronics (32). By displacing the calibrating sensor (31) into various positions 0-1-2-3-4, the accuracy of the machine settings can be checked, whereby optimum utilisation of the same is possible. The bar tension sensor according to the invention consequently permits continual quality control of the injection mouldings, as well as satisfactory monitoring of the machine installation. In addition, it can be fitted new or retrofitted.

Abstract: In order to coat the surface of a body, said body is covered with an envelope comprising at least one fusible active substance and a binder and, in vacuo or in an inert atmosphere, is first heated to a temperature by which the envelope is converted into a porous covering layer with an outer crust. The temperature is then raised until the fusible active substance contained in the cover layer has evaporated. On the one hand, the fusible active substance seals the outside of the covering layer, and on the other hand the fusible active substance generates the coated surface of the body. After the body has cooled, the remains of the covering layer are removed. The body is provided with a non-porous, robust surface.

Abstract: In a process for separating soot particles from an exhaust gas stream, in particular from the exhaust gas of a stationary internal combustion engine, the exhaust gas flows through between separator plates for precipitating soot. It flows here through a plurality of coarse-pored plates (1) of fibres (3) which are braided, laid at random or knitted. With a reduction in the free pore cross-section, soot particles attach to the fibres (3) from which they are detached again in the form of larger particles with increasing layer thickness. These particles which are greater than the soot particles impinging on the plate (1) are subsequently precipitated out of the exhaust gas stream. <IMAGE>

Abstract: In a level detector (17), a bias voltage is developed by a bias current to have a substantially constant difference irrespective of a temperature variation from a detected voltage produced by detecting a device output signal for use in TDM modulation. A control signal generator (19) calculates a substantially temperature independent difference digital value by subtracting from a first digital value of the detected voltage a second digital value of the bias voltage to produce an attenuation control analog level used in controlling a variable attenuator (11) which deals with a device input signal to produce an attenuator output signal with a desired value for use as the device output signal. Preferably, the detected and the bias voltages are amplified by a variable gain amplifier (35) controlled by a processor output signal.
